Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 20, 2024The c.1183A>G (p.I395V) alteration is located in exon 15 (coding exon 15) of the SDAD1 gene. This alteration results from a A to G substitution at nucleotide position 1183, causing the isoleucine (I) at amino acid position 395 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
